<PRE><B>Question 547525</B>
(1/4)x +(1/5)y = 3/5

LCD = 20
multiply by LCD
1*20/4x +1*20/5y = 3*20/5
5x+4y=12
3x-6y=24

5	x	+	4	y	=	12	.............1	
-6	y	=	24		-3	x	---------2	
/	-6	=						
	y	=	-4	+	0.5	x		
Substitute y in 		(1)						
5	x	+	4	(	-4	+	0.5	x
5	x		-16	+	2	x	=	12
5	x	+	2	x	=	12	16	
7	x	=	28					
/	7							
x=	4							
Plug the value of x in (1)								
5	x	+	4	y	=	12		
5	*	4	+	4	y	=	12	
20	+	4	y	=	12			
4	y	=	-8					
/	4							
y=	-2
